Integrated multi-scale and multi-physics modeling is key for enhancing Additive Manufacturing (AM) process understanding and developing relevant controls for manufacturing. This presentation provides an approach where general principles governing physical phenomena and traditionally confined to non-AM domains can be leveraged successfully for AM process modeling. Through illustrative examples, this presentation will demonstrate how fundamental models from thermodynamics, fluid dynamics, and material science can be integrated into modeling AM processes. For instance, the study of melt pool dynamics, commonly used in coating, welding, and casting, can be adapted to enhance the understanding and control of melt pools in AM. Similarly, knowledge of dislocation dynamics and plasticity, crucial for analyzing dwell fatigue and thermo-mechanical fatigue, can be leveraged to develop predictive models for estimating the fatigue life of AM components. Development of integrated physics-based models is traditionally resource-intensive, however, the examples shown here demonstrate that cross-disciplinary physics can be leveraged for AM. |
